crash when trying to upgrade from 2.0.x to 2.3.x
Hello,
I'm trying to migrate dovecot mail database from 2.0.9 on Linux to 2.3.20 on FreeBSD. I've rsync'd the entire database, grabbed all the configs, changed the paths and permission, but when trying to access the mail from Thunderbird I have reproducible crash in the logs:

There's an older thread here mentioning that probably doveadm force-resync would help, but it doesn't fix this. Is there something that could be done here ? I've also reported this in the FreeBSD bugtracker, but just in case decided to ask here too.

Seems like I'm using ... squat, and this, in turn, seems to be the old legacy piece from who knows how long ago installed instance. From your question - am I right supposing that if I will get rid of squat things will improve ? Also seems like it's worth mentioning that downgrading to dovecot 2.3.15 improved things radically - no crash at this time (with the same set of configuration files).

Thanks.

squat has been obsoleted since 2.3.0. You should use either solr or lucene (if it works), there is also xapian based flatcurve plugin available for 2.3 from community (will be in core for 2.4).
